' SERVING-WAGON;

A Applicationiled January 22, 1919. Serial No. 272,440. p

To allwhom t may Concern). Y f v` Be ittknown that I, JESSE' C. WELCH, acitizen of the United States, and resident of the city Vof Tacoma,county of Pierce,and State'of Vashin ton, have invented Acertain new anduseful mprovements inf Serving- Wagons, of whichthe following is aspecication.

This invention relates to improvements in serving wagons,and has for itsprincipal object to provide'for an improved and novel construction in Vadevice of this character, to provide a hubless vehicle wheel, which ismounted upon rollers, to provide a serving car fin which the spaceintermediate the wheels Vis inclosed and contains -receptacles whichkare slidable in a direction parallel with the axis of the wheels.V Otherobjects will be disclosed as my device is more fully explained in thefollowing specification,

` illustrated in the accompanying `drawings .some instances, as isillustrated in and pointed out in the appended claims.

Figure 1 is a side elevation of my device with parts broken away.

Fig. 2 is asectional plan View of Fig. 1; Fig. 3 is a part sectionalelevation of same.

Vhaving a modified form of interior frame.

Referring more particularly to the drawings numeral 1 indicates sideframes of the serving car. The frames are spaced in parallelrelationship and are joined together by end frames 2, thus forming arectangular body. The body thus formed is mounted upon a hollow innerframe 3, which passes transversely lthrough the said body, the saidframe preferably being rectangular in cross section, but I do not wishto Vlimit it to this particular sha e, as .in ig. 6, it isdesirable tomake the frame circular.

Inner frame 3 is shown with its sides inclined' obliquely, and extendsbeyond the side frames at either end. This position may be changed asdesired. A series of roller carriers 4, are mounted upon the inner frame3 beyond theV side faces of the frame l and revolubly support` a roller5. By means of a threaded mounting 5', `the rollers may be adjustedVinwardly or out-V wardly to facilitate removing or placing the wheelsinfposition.

"It will be understood that the rollers 5 are arranged in two groupsthese being shown ascontaining four each, and that the rollers in eachgroup lie in a plane which isV parallel `with the side ,framesV 1. Theinner frame 3 is stationary with respect to the body and being hollow,is utilized for holding slidablecabinets 6 within which are mountedshelves 7 for supporting dishes `and the like.- f

rlhe cabinets 6 are slidable within the Pateateanee. e, mie.l

ner frame 3, and may be partially withdrawn or completely removed asdesired..

The outer ends of cabinets 6 are closed by means of doors 8.

rIhe ends of the bodylare supported upon weight of the body V rests uponthe hubless wheels as will be more fully described later.

Hubless wheels are mounted one upon each group 0f rollers 5, and eachconsists of the circular rim 10, upon the outer periphery of which atire 11 is mounted, and upon the inner periphery of which a circularrail 12 is fastened. The web of the rail 12 fits into grooves 13 of therollers 5, thus forming a tractive surface for the said rollers. It willbe. understood that the tire 11 bears against the floor, and as the bodyis pushed forward, the wheels revolve about the inner frame My peculiararrangement and construction of the wheels and their mountings upon therevoluble rollers constitute a noiseless and nearly frictionless formVof vehicle wheel, which whilehere shown on a serving wagon, yet isapplicable to many other uses. In itself, apart from the serving wagon,the wheel constitutes the most important feature of my device.

The construction of my wheel and the inner frame permit of theelimination of an axle for the said wheels, and also permit of thebetter utilization of the space usually occupied by the axle than couldbe made otherwise.

Tle outer face of each wheel 10 is inclosed by the periphery of an endpiece 15 whichy is fixed to and extends beyond the edge of the frame 3,theY members 15 being provided with the doors 8 previously mentioned topermit access to the shelves 7.

intermediate the side frame is utilized for shelves 16, etc., for thepurpose of storing and carrying any desired articles.

In F ig. 6 I have illustrated a circular inner frame 3 which I prefer touse in some instances and Which is mounted similarly to the rectangularframe 3 and serves in the same capacity. y

Many minor changes may be made inthe construction of my device as hereinillustrat-ed and described, Without departing from the scope of myinvention, and I do notvvish tobe limited eXcept in accordance With theappended claims. Y

What I claim as my invention is:

1. A vehicle comprising` a body, an inner frame extending beyond thesides of the said body, rollers mounted upon the extending end of thesaid inner frame, hubless Wheel means mounted upon the said rollers;said Wheelmeans comprising a circular` rim, a tire mounted upon theouter periphery of the said rim, anda circular rail secured to the innerperiphery of the said Wheel, Whereby. the Wheel is revolubly held incontact ,With the said rollers.

la pair of end it'ramesfconnecting the said side frames, a rectangularinner frame ar ranged transversely of and extending beyond said sideJframes, cabinets slidably mounted Withinthe said inner frame, rollersarranged in a parallel group and secured totheend of the said innerframe,vvheel of rollers; said'means embodying a circular rim, a tiremounted upon the outer periph-V ery of the said rim, a circular railmounted upon lthe inner periphery of the said riin and in contact Withthe said rollers, wherebyV the -vvheel may revolve upon the rollers.

" means revolubly mounted upon said groupl 3. A service car comprising abody, two Y Wheels consistingY of rings having inner and Y outer treads,vbearing devices carried by the casing and engaging the inner treads,the. casing having compartments accessible through the central openingsof the Wheels and other compartments accessible from the sides of thecasing outside of ltheareaof said Wheels.

Signed at Tacoma, Washington, thisr 16th day of January, 1919. Y y
